Comprehensive analysis of Poly(A) tails in Mouse Testes and Ovaries using Nanopore direct RNA Sequencing. 

ABSTRACT: Germ cell development, gametogenesis, is a complex process in which dysfunction leads to infertility, a growing health and sociological problem worldwide. In both spermatogenesis and oogenesis, post-transcriptional gene expression regulation is crucial. Essentially, all mRNAs possess non-templated poly(A) tails, which composition and dynamics (elongation, shortening, and modifications) determine the fate of mRNA. In this context, we present a comprehensive transcriptomic dataset that focuses on mRNA poly(A) tails metabolism in murine testes. Analyzed RNA samples are isolated from wild-type and transgenic mice lacking TENT5C polymerase, which can extend poly(A) tails in the cytoplasm. Both whole testes material, as well as male gametes at different developmental stages (round or long spermatids) were analyzed.

Drosophila Testis Proteome - Stage-specific testes proteomics of Drosophila melanogaster identifies essential proteins for male fertility

Project description:Spermiogenesis in Drosophila melanogaster is a highly conserved process and essential for male fertility. In this haploid phase of spermatogenesis, motile sperm are assembled from round cells, flagella are assembled, and needle-shaped nuclei with highly compacted genomes are formed. We aimed at identifying proteins relevant for the maturation phase from spermatids to sperm. As transcription takes place mainly in spermatocytes, and transcripts with relevance for post-meiotic sperm development are translationally repressed for days, we comparatively analysed the prote-ome of larval testes (stages before meiotic divisions), of testes of 1–2-day-old pupae (meiotic and early spermatid stages) and adult flies (late spermatids and sperm). We identified 6677 pro-teins, with 422 solely detected in larval testes, 623 in pupal testes and 634 in adult testes. We analysed a few so far uncharacterized proteins with repect to stage specific expression and im-portance for male fertility. For example, Mst84B (gene CG1988), a very basic cysteine- and lysine-rich nuclear protein, was present in the phase of transition from a histone-based to a pro-tamine-based chromatin structure. CG6332 encodes d-Theg, which is related to the mouse tHEG and human THEG proteins. Mutants of d-Theg lacked sperm in the seminal vesicles and were sterile. The identification of numerous predicted proteins underscores the high potential of pro-teome analysis for future analyses of spermatogenesis.

Global gene expression comparation among testes, ovaries, Smad4flox/floxMerCreMer Stra8+/− ovaries and Smad4flox/floxMerCreMer Stra8−/− ovaries

Project description:To confirm that female-to-male sexual fate reversal in Smad4flox/floxMerCreMer Stra8−/− ovaries occurs independently of somatic environment. We analyzed transcriptome of samples using RNA from control testes, ovaries, Smad4flox/floxMerCreMer Stra8+/− and Smad4flox/floxMerCreMer Stra8−/− ovaries.

Drosophila melanogaster late third instar larval testes and gonadal fatbody RNA-seq profiling

Project description:In order to study the effect of protease treatment on dissected testes, we performed different strategies of cleaning and dissociation on Drosophila melanogaster w1118 larval testes. We collected testes without protease treatment with fatbody just attached around the gonad, fatbody alone dissected from around the testes, testes without fatbody and testes dissociated by either by Papain or Trypsin and Collagenase cocktail. We prepared poly A+ RNA-Seq libraries and performed transcriptional profiling to generate 50 bp stranded single end reads.

Unbiased screen of RNA tailing enzymes reveals a poly(UG) polymerase required for genome integrity and RNA silencing

Project description:Ribonucleotidyl transferases (rNTases) add non-templated ribonucleotides to diverse RNAs. We developed a screening strategy in S. cerevisiae to identify sequences added by candidate enzymes from different organisms at single-nucleotide resolution. The rNTase activities of 19 previously unexplored enzymes were determined. In addition to poly(A)- and poly(U)-adding enzymes, we identified a C-adding enzyme that is likely part of a two-enzyme system that adds CCA to tRNAs in a eukaryote; a nucleotidyl transferase that adds nucleotides to RNA without apparent nucleotide preference; and a poly(UG) polymerase, C. elegans MUT-2, which adds alternating U and G nucleotides to form poly(UG) tails. MUT-2 is known to be required for certain forms of RNA silencing, and mutations in the enzyme that are defective in silencing also fail to add poly(UG) tails in our assay. We propose that MUT-2 poly(UG) polymerase activity is required to promote genome integrity and RNA silencing.

Ribosome profiling study of Miwi-null testes

Project description:piRNAs are a novel class of small noncoding RNAs that were recently identified in animal germ cells. This class of small noncoding RNAs is specifically associated with an evolutionarily conserved PIWI family proteins, which belong to the germline-specific members of the Argonaute protein family and are indispensable to germline development in animals. The PIWI/piRNA pathway has been deemed as an innate immune system that prevents mobile genetic elements from destabilizing DNA and that protects genome integrity in animal germ cells. By ribosome profiling using Miwi-null testes, we identified a group of ~600 mRNAs as likely direct piRNA targets for translational regulation in mouse spermatids. These results suggest that the mouse PIWI (MIWI)/piRNA is responsible for activating translation of a subset of spermiogenic mRNAs to coordinate with morphological transformation into elongated spermatids.

Comparison of gene expression in wild type Drosophila testes with various meiotic arrest mutants

Comparison of gene expression in wild type Drosophila testes with various meiotic arrest mutants

Project description:The expression of a very large number of genes changes as male germ cells pass through differentiation into spermatids and then sperm. Much of this transcriptional programme requires the activity of the meiotic arrest genes. We extracted RNA from wild type testes, as well as aly mutants and Nxt1 mutants, and used microarrays to compare gene expression profiles. We dissected testes from 0-1 day old Drosophila males, taking care to remove accessory glands and ejaculatory ducts. The control sample expressed a tin-RNAi construct, and had normal testes. The aly mutant were homozygous for aly[5]. The Nxt1 mutants were Nxt1[z2-0488]/Nxt1[DG05102].
